The design and synthesis of azogabazine is described, which represents a highly potent (IC50 = 23 nM) photoswitchable antagonist of the GABAA receptor. An azologization strategy is adopted, in which a benzyl phenyl ether in a high affinity gabazine analogue is replaced by an azobenzene, with resultant retention of antagonist potency. We show that cycling from blue to UV light, switching between trans
描述了 azogabazine 的设计和合成,它代表 GABA A受体的高效 (IC 50 = 23 nM) 光开关拮抗剂。采用偶氮化策略,其中高亲和力gabazine类似物中的苄基苯基醚被偶氮苯取代,从而保留拮抗剂效力。我们表明,从蓝光到紫外光的循环,反式和顺式异构形式之间的切换,会导致 GABA 离子通道的光化学控制拮抗作用。
